How to convert byte to string in C++?

In C++, you can use the stringstream class to convert a byte array to a string. Here is an example code:

#include <iostream>
#include <sstream>

int main() {
    unsigned char bytes[] = {0x48, 0x65, 0x6C, 0x6C, 0x6F}; // byte数组
    std::stringstream ss;

    for(int i = 0; i < 5; i++) {
        ss << bytes[i]; // 将每个字节转换为字符
    }

    std::string str = ss.str(); // 将stringstream中的内容转换为string

    std::cout << "Byte array converted to string: " << str << std::endl;

    return 0;
}

In this example, we are converting a byte array to a string and outputting it to the console. The content and length of the byte array can be modified accordingly for the conversion.
